IMPROVED MEAT-MINGER.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JEAN Mania Dnournn,- of Oarondelct, in the county of St Louis, and State of Missouri, have invented certain new and useful Improvements in- Meat-h'lincing Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings making part of this specification, in which I Figure 1 is a front elevation.

Figure 2, a side elevation.

Figure 3, asection of cylinders through line y y, fig. 1.

Figure 4, a section of the same through line as x, fig. 2.

Figure 5 are shafts, having attachments, and operating as hereafter descr ibedr Figure 6 is a detached view of a cam-wheel, 'v, fig. 2.

The nature of my improvements relates to the construction and arrangement of the apparatus by which the meat is at first cut, and also to the device by which is afterwards ejected from the machine; andin order that thc same may beclearly understood, I will proceed to describe it in detail.

The body of my machine consists of three communicating hollow metallic cylinders, 5. b b, ranged above one another, as shown in figs. 2 and 4, for convenience madeat first in two separate sections, each of the form shown in fig. 3, and afterwards joined together, and to the end-plates A A, by belts or screws, c.e e ef.

In figs. 2 and 4, G is the hopper with which the top cylinder is provided, for the reception of meat.- aid represent alternategrooves and ridges, of about the form shown, fig. 3, around theintcriorsurfaces of the top and middle cylinders. The grooves in the top cylinder are wider, and the ridges further apart, than those in the second.

The bottom cylinder, 5, has a smooth interior surface. The bore ofthis cylinder extends the whole length of the cylinder, and the ends of the top and middle cylinders are closed by the formations, Zc, journals for shafts which revolve in these cylinders, being provided at each end. An opening, g, of the diameter of the hereof the bottom cylinder, in the end-plate A, communicates with ,it.

2'2" are shafts, which revolve in the top and middle cylinders, provided with cutters, m, at different dis tances, to correspond with the centres of the grooves through which they move. i

The ends of the shafts passing through the end-plates are provided with pinions, a n, on the' front ends,

' gearing together, as at fig. 1.

The cutters m are of an almost semicircular form, sharpened on the edges, arc provided with the hafts'm", which pass through the shafts, and extend thence a short distance, as seen at fig. 4, and are so arranged as to operate eccentrically.

Attached to the shaft 1' are drivers, of sheet metal, 7', which may be all 'made of one piece of metal, of the form of the grooves through which they pass. 7 v l l V The ends of the knife-ha-fts of thcshaft (of the middle cylinder) are sharpened, as shown at S, -fig. 4.

T is a piston, opcra-ting-inthc lower cylinder by means of the cam V, on the rear end of the shaft 2', but does not move forward beyond the point,K', fig. 3, lest anything might drop behind it and clog it up.

T is a spiral spring, wound round the piston-rod T to force it back, one end resting against the end-plate A, the other against the head U ofthc piston-rod.

The cam V consists of a round wheel, with a gradually rising ridge on the face V, terminating in an abrupt fall, V. The rise of the ridge pushes the piston forward, while the abrupt termination allows it to spring back. i v v i The cam has a handle, j,.by which it is operated, the one application of power moving the piston, and revolving the shafts, which revolve in contrary directions. v p

U are the legs or supports of the whole machine, and Z the feet, which may be fastened to the floor by screws.

The meat, being placed in the hopper, is cut by the knives gradually, as it passes through the first and second cylinders. The knives on the first shaft revolve from right to left with it, those on the second from .left to right,though without any material difference in the arrangement of parts the movements could be reversed. The meat is conveyed from the first to the second cylinder by the drivers, and, being minced to the requisite fineness, is dropped into the third cylinder, out of which it is ejected by the piston.

This machine maybe used not only in cutting meat, but to considerable advantage in cutting vegetables, and is especially a valuable aid in the making of julienne. i

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the cutters m, drivers 7', shafts i 2', cylinders b I)" Z), all constructed and arranged substantially in the manner and for. the purpose set forth.

2. The piston T, spring T, and cam V, constructed, arranged, and operating together, substantially as specified. v y 3. The combination of the different parts herein specified, arranged substantially as described and for the purpose set forth.
